###### Number Operation

###### Computation

###### Solve multi-step problems within 1,000 (addition, subtraction, multiplication, and division).

:

###### Supporting targets:

###### 1:

Solve problems that have more than one operation.

###### 2:

Understand that the presence of parenthesis in an arithmetic equation signals for this part of the problem to be solved first.

###### 3:

Understand that the order of operations must be followed to evaluate expressions.

###### 4:

Define PEMDAS – Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.

###### 5:

###### Grade:

4th

###### Vocabulary:

PEMDAS, Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction, Operation

Activities:

1. Students used what they understood of the order of operations to solve given expressions.

2. Students were able to choose the operation to determine the outcome of some expressions.

###### Geometry

###### Symmetry

###### Recognize a line of symmetry for a 2D figure as a line across that divides a figure into two congruent parts.

:

###### Supporting targets:

###### 1:

Understand that a figure can have multiple lines of symmetry.

###### 2:

Understand that a figure can have no lines of symmetry.

###### 3:

###### 4:

###### 5:

###### Grade:

4th

###### Vocabulary:

Symmetry, Line of Symmetry, Hexagon, Trapezoid, Rhombus, Square, Rectangle, Congruent, Reflection

Activities:

1. Students used pattern blocks to create a symmetrical image with one identified line of symmetry. Students had to find the other lines of symmetry if there were any more.

2. Students then used the pattern blocks to create a symmetrical 2D figure with lines of symmetry.
